At the heart of computing are tiny crystals that transmit and store digital information’s ones and zeroes. Today these are hard and brittle materials. But cheap, flexible, nontoxic organic molecules may play a role in the future of hardware.
A team led by the University of Washington in Seattle and the Southeast University in China discovered a molecule that shows promise as an organic alternative to today’s silicon-based semiconductors. The findings, published this week in the journal Science, display properties that make it well suited to a wide range of applications in memory, sensing and low-cost energy storage. (more…)
For Devin Naar, the Sephardic Studies Initiative is not just a valuable historical archive; it has also been a personal journey revealing an untold family story from the years of the Third Reich.
Naar’s part of the story began about 10 years ago, when as an undergraduate at Washington University he grew interested in the history of Turkey and Greece, which for centuries until World War I was part of the Ottoman Empire. His family comes from Salonica, a port city in Northern Greece. (more…)
A study dating the age of more than 1 million single-letter variations in the human DNA code reveals that most of these mutations are of recent origin, evolutionarily speaking. These kinds of mutations change one nucleotide – an A, C, T or G – in the DNA sequence. Over 86 percent of the harmful protein-coding mutations of this type arose in humans just during the past 5,000 to 10,000 years.
Some of the remaining mutations of this nature may have no effect on people, and a few might be beneficial, according to the project researchers. While each specific mutation is rare, the findings suggest that the human population acquired an abundance of these single-nucleotide genetic variants in a relatively short time. (more…)
Microsoft commemorates 30th Employee Giving Campaign with CEO Steve Ballmer and Chairman and Founder Bill Gates.
REDMOND, Wash. — Oct. 18, 2012 — Microsoft Corp. today commemorated its 30th Employee Giving Campaign and announced that U.S. employees raised $1 billion in cash since 1983 for approximately 31,000 nonprofits and community organizations around the world. CEO Steve Ballmer announced the milestone during a special town hall event at the Microsoft Redmond campus, which included Microsoft Chairman Bill Gates and Washington State Gov. Chris Gregoire.
“Today, I’m thrilled to announce that since our Employee Giving Campaign started in 1983, Microsoft employees have donated a total of $1 billion to more than 31,000 nonprofits around the world,” Ballmer said. “I’m incredibly proud of our employees, and this is truly a time to celebrate, not just because we’ve raised a record amount of funds, but also because together with our nonprofit partners, we have impacted and improved the lives of hundreds of millions of people.” (more…)
COLUMBUS, Ohio – Transportation practices tend to be more environmentally friendly in wealthier metropolitan areas located within states that mandate comprehensive planning, new research suggests.
The study involved an examination of 225 U.S. metropolitan areas between 1980 and 2008 to gauge how sustainable their transportation practices were and determine what kinds of socioeconomic factors appeared to influence those practices. (more…)
The past few months have seen a spate of solar flares – bringing spectacular views of the northern lights as far south as Seattle – along with media speculation that the electrical activity could disrupt power grids, satellites or ground airplanes.
John Sahr, a UW professor of electrical engineering who studies the upper atmosphere, is the regional go-to guy for such questions. We found some time in Sahr’s busy schedule (he’s also the UW’s associate dean of undergraduate academic affairs and a part-time zombie hunter) to get his read on the space weather forecast. (more…)
*Meet the Force-sensitive fans who helped bring the Star Wars universe to life in “Kinect Star Wars,” the ultimate Jedi experience for Padawans of all ages.*
REDMOND, Wash. – Abby Lee walked into a Seattle toy store recently and purchased two LEGO Darth Vader alarm clocks, a Star Wars pop-up book, and a few LEGO speeder bikes. The bemused checkout clerk asked if she was going to a birthday party.
In ancient Earth history, the sun burned as much as 30 percent dimmer than it does now. Theoretically that should have encased the planet in ice, but there is geologic evidence for rivers and ocean sediments between 2 billion and 4 billion years ago.
Scientists have speculated that temperatures warm enough to maintain liquid water were the result of a much thicker atmosphere, high concentrations of greenhouse gases or a combination of the two. (more…)
